Special characters in reprex

[filipwastberg]

I was trying to post an issue for another package about special characters when my reprex() failed because of those characters:

reprex::reprex({
  
  library(dplyr)
  
  iris %>% 
    mutate(Species = gsub("a", "å", Species)) %>% 
    group_by(Species) %>% 
    count()
  
})   

The output from the reprex is:

library(dplyr)

iris %>% 
  mutate(Species = gsub("a", "
#> Error: <text>:5:30: unexpected INCOMPLETE_STRING
#> 4: iris %>% 
#> 5:   mutate(Species = gsub("a", "
#>                                 ^

The code runs fine outside of the reprex, any idea why it fails inside?

I am unable to reproduce this on Windows.

When I execute your exact code, I get a successful reprex.

I think between:

• use of knitr version 1.23
• Use read_utf8() and write_utf8() #237
• Specify UTF-8 encoding to rmarkdown::render() #261

reprex is handling encoding as well as its dependencies allow (mostly especially the difficulties around encoding on Windows in R itself). I'm closing this. If anyone has a new challenging example, especially one that fails with dev reprex + knitr v1.23, please add it to #262.
